- 1 Claim.

- The present invention relates to window structures and is particularly concerned with windows of the sash type.

One of the objects of the invention is the provision of an improved structure for support.- ing and guiding windows of the sash type in such manner that the builders may dispense with the usual ropes, pulleys, and sash weights of the prior art, the sashes being held in, any adjusted position by means of a plurality of sprin pressed friction members.

Another object of the invention is. the provision of an improved window sash structure which is so arranged that each sash with its. guides may be installed or removed as a. unit so as to facilitate the cleaning or painting of, the windows or sashes, and to eliminate. the. hazards which have, been found with the devices of theprior art where it has been. necessary to clean or paint the windows or sashes. from. the outside.

Another object of the invention is the provision of an improved sliding sash unit by means. of which any sash may be guided for maintainin an effective closure of the window frame and by means of which the sash is automatically held in any adjusted position.

Another object of the invention is the provision of improved sash hardware which is sturdy, capable of use for a long period of time. without necessity for repair or replacement of parts, and adapted to be manufactured at a low cost, so that. itmay be capable of extensive use.

Another object of the invention is the provision of an improved sash supporting; structurewhich is practically weather-tight and by means. of which the sashes are supported'so-that'they can always be easily opened or closed or moved to any desired adjusted position. 7

Other objects and advantages, of our invention will appear more fully from the following description and from the accompanying drawings, in which similar characters of reference indicate similar parts throughout the several views.

Referring to the drawings, of which there are Figure 1 is a fragmentary vertical sectional view through a window frame and sash structure embodying the invention taken on. the plane which passes at right angles to the wall within which the window frame is located Fig. 2 is a fragmentary elevational view in par tial section taken on the plane. of the line. 2-2 of Fig. 1 looking in the directionof the arrows;

Fig. 3 is azfragmentary horizontal sectional to view taken on the plane of the line 33 of Fig. 1 looking in the direction of the arrows;

Fig. 4 is a fragmentary horizontal sectional view taken on the pane of the line 4-4 of Fig. 2 looking in the direction of the arrows and showing the spring-pressed friction devices for holding the sash in adjusted position;

Fig. 5 is a view in perspective of one of the metallic guide members for the sash;

Fig. 6' is a view in perspective of one of the wooden slider members which is attached to the sash for guiding it in the guide members of Fig. 5-; and

Fig. 7 is a view in perspective of one of th spring-pressed plunger members carried by the sliders of Fig. 6 for holding the sash in anyadj'usted position. 1

The present sash hardware may be used on practically any type of sash windows and it is. illustrated inconnection with a window frame the upper rail of which is indicated at In, the frame sill at H, and side frame members or uprights at l2. The upper sash is indicated in its entirety by the numeral l3. and the lowersash. by the numeral l4.

The sash to be used according to. the present invention is or narrower width than the space between the uprights or-side framemembers 12. by an amount sufiicient. to'accommodate a. pair of the slider members [5 (Fig; 6) one. of which is to. be'attached to each side of each sash.

The slider members l5. are. adapted to be slidablyreceived within; the channels I6, I! which are located on each side of the frame for slidably' supporting the sash. I3, I l.

The. channels IS, IT preferably comprise sheet metal members made of suitable metal. such as steel or copper or spring bronze and the channeled members are preferably of thesame shape but are oppositely disposed. Thus each channel member has; a. relatively wide body flange It which is slightly wider than the width of the slider i5 and a pair of edge flanges I9, 20 at right an les to the body flange l8. 1

The width of the edge flanges I9, 20 is pref. erably such that the relatively narrow edge-portions 2|, 22 of each slider 15 may be received inside the channel. Each edge flange l9 and ZB. carries an inwardly directed retaining flange 23 and 24, respectively, and these flanges extendat right angles to the edge-flanges l9 and 2.0., and are. paral lelto the. body flange l8. I

The sliders l5 are preferably made. of relatively hard wood and they comprise elongated strips of lumber which are substantially recthat there is a clearance on both sides of the flanges 23 and 24 when the sliders 15 are attached to the sashes. This leaves a member of substantially rectangular cross section having a projecting portion 21 at the middle of one side for engaging the edge of the sash. Y

'Each slider is provided with a 'plurali"ty, dff

channels l6. These recesses are deep enough so apertures 28 for receiving the wood screws 29 by means of which it is attached to the edge of a sash. The sliders [5 are preferably of substantially the same length as the sash to which they are attached, while the channels is are preferably of substantially the same length astheinil I I proper width so that when the sliders l5 are attached at each side of the sash, the sash and side vertical space in the window frame;

a substantially U-shaped weather-strip 42 which has outwardly extending attaching flanges 43 secured to the sill II. A similar weather-strip 44 is arranged at the top for engagement in a groove in the top rail of the top sash 13.

The frame is provided with the usual inner window stop 41 which may be secured in place Thus the channels preferably extend from the. i

bottom to the top of the frame while thesliders I extend from the bottom to the top of each sashbut in some embodiments of the'invention the sliders or the, channels may be made shorter since they may still effect their guiding function even though they are shorter. The channels however preferably go from top to bottom so that the edge of the sash at the window frame is completely enclosed at all times and there is no chance of cracks existing between the sash and the window; frame at any time.

In order to hold each sash in its adjusted position, the sash is preferably provided with aplurality of spring-pressed friction devices such as the plungers 30 located in the bores 3! in the sliders l5 and engaged by the helical springs 32. Any suitable number of these plungers may be used and the number .used depends upon the strength of the springs and the weight of the sash as the friction must be increased for the heavier sash-and this can be done in some measure by increasing the spring tension or it can be done by using a greater number of plungers.

Each plunger 30 preferably has a cylindrical head 33 which may have a sliding fit. in the bore 3| and each plunger preferably has a cylindrical shank 34 which is adapted to be received inside the end of the helical spring 32 to serve-as a guide for the spring. The other end of the spring 32 engages the end 35 of its bore 3| and the springs are under initial compression when the slider is inserted in its channelso that the plane end 36 of each plunger engages the flat inner. surface of the flange [9 or 20 and acts as a brake shoe to prevent the sliding movement'of thesash.

The plungers 30 may be made of relatively hard wood or they may be formed'out of a phenolic condensation compound or material. e l

The friction'between the ends 33 of the'plungers and the channel is sufficient to hold the sash in any adjusted position but not sufficient to prevent positive movement of the sash by an operator.

At the juncture between the upper and lower sash, the installation is preferably provided with strip 38 is. carried by the upper rail 40 0f the lower sash. I V At the bottom, thebottom rail of the lower sash I4 is preferably grooved at 4| for receiving The assembly of my window structure is as follows: Each sash is preferably trimmed to sliders will slide readily in the channels Hi When theyare placed in the window frame between the stops 46and- 47. The sliders are attached to the edge of the' sash by means of the wood screws 29 and the channels l6'a-re then slid endwise on the sliders l5, one channel being used at each side. As the channels are slid on the sliders, the'springs 32 and plungers 30 are placed,

in their bores 3l,.and the plungers are pressed inwardly until they can be received in the'chan- V nel. 1

Assuming for example that the upper sash has been assembled with its sliders, channels and plungers, theflplungers will retain the channels in any adjusted'position and the channels may be moved to such a position that they project equally from both ends of the sash. I Then the sash audits channels maybe handled as a unit and placed in the window frame against the stop 46 in the position shown in Fig. 3. The nextfor lower sash may then be assembled with its sliders, plungers and channels, and placed in, the frame in its .proper position. Then both channels by removing the screws of the window stop '41.

The operation of th window structure is'as followsz.

The channels l 6 engaging the sliders" l5 actas" weather-strips at the edge of each sash and since the wooden sliders engage metal channels, the

sash will slide .more readily than the devices of the prior art where wood engages wood."- No I sash, weights, cords or pulleys'need beused and other non-metallic friction is only slightly more than enough 'to 1 hold the sash in its adjusted position. The sash will then be held whereit is placed'by means' of the spring' pressed plungers 30. Wheni'the sash is closed, the operator need only. exert a, relatively small force as the weight of thesash I is added to his efforts in forcingthe sash downwardly. V It will thus be observed that the present win.- dow structure permits the sash'to be removed as a unit with its guides whenever it isde'sired to wash the sash or paint it and the present. in-

stallation accomplishes the same purposes with-i out the use of any sash weights, pulleys, or-ropes: It may be used upon, simpler'types of window frames since they do not require a box for the sash weights and the present structure greatly reduces the expense of installation of the window sashes.

The sliding action of the sash in its present structure is much more certain and dependable and there is less possibility of the sash sticking in its guides than with the devices of the prior art where the edge of the sash had sliding engagement with wood surfaces that are usually painted. The present window structure may be used for a long period of time without necessity for repair or replacement of any of its parts and it is not necessary to paint the metallic parts of the window since they may be made out of steel or other meta1 suitably treated to resist corrosion.

Since the screws which attach the sash to its guides have their heads located inside the channels, these screws are not visible and cannot be removed from the outside by unauthorized persons.

Whil we have illustrated a preferred embodiment of our invention, many modifications may be made without departing from the spirit of the invention, and we do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of all changes within the scope of the appended claim.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent of the United States, is:

In a window frame having outer and inner stops and having oppositely disposed vertical frame members, a pair of channelled sheet metal guide members located between the stops ad- 1 jacent each vertica1 frame member of the window frame, said channelled guide members being of substantially rectangular shape in cross section and having inwardly extending flanges on the side adjacent the sash, said flanges being spaced from each other to provide an opening in each channel, a wooden slider member having a sliding lit in each of said channels, said slider member being provided with a plurality of transversely extending bores and said bores being provided with friction plungers engaged by compression springs in said bores to place sufiicient friction between said plungers and one of the side flanges of each of said channelled members to hold a sash in any predetermined adjusted position, each of said slider members comprising an integral strip of greater width than the win dow sash to which it is attached to extend
